Seas T29MF001 E0047-04 Magnum Tweeter - Excel Series

The SEAS T29MF001 E0047-04 “MAGNUM” is a 25mm magnesium dome tweeter with a patented Neodymium based magnet system. It gives extremely precise and realistic sound reproduction combined with a relatively low crossover frequency.

The SEAS HEXADYM patented magnet system is used based on 6 radially magnetized NdFeB magnet blocks, and confers efficient ventilation and damping of every potentially resonant cavity behind the dome, surround and voice coil. Moderate magnetic stray fields present no problems in AV installations.

A generously underhung voice coil ( + and - 0.5mm ) ensures low distortion even with low crossover frequencies is coupled to an optimally shaped magnesium dome membrane which behaves like a piston throughout the audible frequency range and shows a controlled break up above it.

SEAS have designed a homogenous, linear surround from SONOMAX, a soft polymer high stability material. Flexible lead-out wires ensure a good connection between voice coil and terminals. This arrangement also helps to prevent lead breakage due to the large excursions encountered when low crossover frequencies are used.

Low viscosity ferrofluid is used which provides excellent cooling while maintaining a low resonance frequency.

The 6,0 mm machined aluminium front plate has a moderate horn loading characteristic which ensures linear frequency response, and a stiff and stable connection to the cabinet. A substantial injection-moulded rear chamber made from zinc eliminates unwanted chamber wall resonances and conducts heat away from the magnet system.
